Wisconsin is becoming a national hub for data centers. Microsoft has committed $20 billion to a massive campus in Mount Pleasant, and Vantage Data Centers is building a $15 billion facility in Port Washington. More may be on the way — WEC Energy Group's CEO said in May 2026 that the company expects to announce additional data center customers this fall. 

According to an analysis by Clean Wisconsin, the data centers already planned for the state will use enough electricity to power 4.3 million homes — more than every housing unit in Wisconsin. To meet that demand, We Energies is delaying the retirement of coal plants at Oak Creek, planning billions of dollars in new gas-fired power plants, and has paused its near-term carbon reduction goals. Cassie Steiner, senior campaign coordinator for Sierra Club's Wisconsin chapter, put it plainly: "The fossil fuel expansion that we could see from this energy demand growth would mean tragedy for the climate and have huge negative impacts on health and our ability to meet climate goals and air pollution standards."

Both Governor Tony Evers and WEC Energy Group have pledged to go carbon neutral by 2050. Letting data centers lock Wisconsin into decades of new fossil fuel infrastructure makes that promise nearly impossible to keep.

The Wisconsin Public Service Commission (PSC) has authority over how utilities plan and build new energy capacity. We're calling on the PSC and Governor Evers to require that any new power built specifically to serve data centers in Wisconsin come from clean, renewable sources. Microsoft, Vantage, and the tech companies that follow them have the resources to invest in clean energy. Wisconsin can't absorb the climate and health costs of powering their operations with coal and gas.

Sign this petition to tell Governor Evers and the Wisconsin Public Service Commission: put the community, public health, and the environment before corporations and profit.
